I-sprocket sisixhobo esiqinileyo okanye esithethiweyo esidibanisa ikhonkco (i-roller) ukuhambisa intshukumo. Ivili lohlobo lwe-sprocket lisetyenziselwa ukubandakanya ibhloko enepitch echanekileyo kwikhonkco okanye intambo yekhonkco.

Imilo yezinyo ye-sprocket kufuneka iqinisekise ukuba ikhonkco ingena kwaye iphuma kwi-meshing kakuhle kwaye igcina amandla, inciphisa impembelelo kunye noxinzelelo loqhagamshelwano lwekhonkco lwekhonkco ngexesha le-meshing, kwaye kufuneka kube lula ukuyiqhuba.

Iiparamitha ezisisiseko zesprocket yipitch, idiameter yangaphandle yerola, inani lamazinyo kunye nenowuthi yomqolo. Isalathiso sesangqa ububanzi, incam yezinyo isangqa idayamitha kunye nezinyo ingcambu isangqa ububanzi sprocket imilinganiselo eziphambili sprocket.
I-sprockets ene-diameters encinci ingenziwa kwisiqwenga esinye; ii-sprockets ezinobubanzi obuphakathi zenziwe kwi-webs okanye iiplate ezixutywe; ii-sprockets ezinobubanzi obukhulu zenziwa kwisakhiwo esidityanisiweyo, rhoqo ngezixhobo zeringi ezinokutshintshwa ezibotshelelwe kwi-hub.

I-sprocket encinci ye-diameter yenziwa ngokubanzi ibe yintlobo edibeneyo, kwaye i-medium-diameter sprocket ngokuqhelekileyo yenziwe ibe yintlobo yepleyiti ethethiweyo. Ukuququzelela ukuphatha, ukulayishwa kunye nokunciphisa ubunzima, umgodi wenziwa kwipleyiti ethethiweyo, kwaye i-sprocket enkulu-diameter ingenziwa ibe luhlobo oludibeneyo. Umsesane kunye nombindi wevili unokwenziwa ngezinto ezahlukeneyo.

Izinto ze-sprocket kufuneka ziqinisekise ukuba amazinyo egiya anamandla okwaneleyo kunye nokunganyangeki, ngoko ke indawo yezinyo ye-sprocket iphathwa ngokutshisa ukuphumeza ubunzima obuthile.
